onCtrlCExitRequest property
void Function()?
onCtrlCExitRequest
getter/setter pair
The SIGINT-parity exit the TUI's ctrl+c press 2 triggers
(issue #830): abort-if-running bounded, session resume hint,
exit 130. bin/fah.dart installs the real routine; null leaves the
legacy plain-quit fallback.
Implementation
void Function()? onCtrlCExitRequest;
